摘　　要：为了保证基于本地信息的基础上,实现不同容量微源对于负荷功率的精确分配,提出了一种改进的类功率下垂控制。通过分析并联微源单元的功率分配机制,定义有功功率和无功功率的线性组合"类功率",其中类有功功率和类无功功率仅与相位差和幅值差相关。根据不同容量微源对于负荷功率的精确分配的要求,选择适当的参数,推出类功率下垂控制。仿真实验证明了该控制策略的有效性与优越性。In order to realize micro-sources of different capacity provide precise power to meet needs of the load baseO on local information, the paper proposes an improved quasi-power droop control. After analyzing power sharing between micro-sources, quasi-power is defined as the linear combination of active power and reactive power. Active quasi-power only relates to the phase difference,while reactive quasi＇power only relates to the amplitude difference. Proper parameters are chosen to satisfy the situation that different capacity provide precise power to meet needs of the load based on local information, which indicates an improved quasi-power droop control. Simulation results show the effectiveness and superi- ority of the proposed method.
